Jobs in the Garden: January 2026

January is one of the coldest months of the year in the UK, with frost, snow, and icy conditions often dominating the garden. While the growing season is still a few months away, there are still important tasks to be done to maintain your garden’s health and prepare it for the year ahead. Here’s a guide to the essential jobs you should be doing in your garden during January.

1. Protect Plants from Frost and Cold Weather

January can bring some of the coldest weather of the year, and frost can damage tender plants. Ensure that any vulnerable plants, particularly those that are not frost-hardy, are protected. You can cover them with horticultural fleece, cloches, or bubble wrap. For potted plants, move them to a sheltered location, or bring them inside if possible. Adding a thick layer of mulch around the base of plants can help to insulate their roots and protect them from extreme cold.

2. Check for Snow and Ice Damage

Heavy snow or freezing temperatures can cause significant damage to trees, shrubs, fences, and garden structures. Regularly check for snow build-up on tree branches or shrubs, as the weight can break branches. If you have snow on your garden, gently shake it off trees and shrubs to avoid breakage. Be mindful of icy conditions around pathways and garden steps, and treat them with grit or salt to prevent slips and falls.

3. Prune Trees and Shrubs

January is a great time to prune certain trees and shrubs, particularly deciduous ones. Pruning now will encourage healthy growth when the warmer months arrive. Remove any dead or damaged wood, and tidy up the overall shape of the plant. Avoid pruning spring-flowering shrubs, as this could reduce the number of flowers they produce later in the season. Always use clean, sharp tools to make cuts and avoid spreading disease.

4. Plan and Prepare for Spring Planting

While the garden may seem dormant, January is the perfect time to plan your garden for the upcoming season. Take time to sketch out your garden layout, order seeds, bulbs, or plants, and make a list of any new projects you’d like to take on. Now is also a great time to start planning what vegetables or flowers you’d like to grow in the spring and to prepare your growing space accordingly. For indoor gardening enthusiasts, consider starting some seeds indoors, such as tomatoes, peppers, or herbs, to get a jump start on the growing season.

5. Feed the Birds and Wildlife

Winter is a tough time for garden wildlife, so continue to provide food and water for birds, hedgehogs, and other creatures. Place bird feeders around your garden and ensure they are well-stocked with seeds, suet balls, or fat cakes. Fresh water is just as important in winter, so keep birdbaths free of ice and fill them with fresh water daily. You can also leave piles of leaves, logs, or branches in quiet corners of the garden to provide shelter for hedgehogs and other small mammals.

6. Maintain and Clean Garden Tools

Winter is the perfect time to clean and maintain your garden tools and equipment. Ensure your spades, forks, and secateurs are sharp and in good condition for the busy growing season ahead. Clean off any dirt, oil moving parts, and check for any signs of wear or damage that might need repair. If you store tools outside, make sure they are properly protected from the elements to prevent rusting.

7. Maintain the Greenhouse

If you have a greenhouse, it’s essential to ensure it’s ready for the colder months. Check for any leaks, broken panes of glass, or areas that may let in drafts. Clean the greenhouse to remove any pests or diseases that may have overwintered. It’s also a good idea to make sure the temperature inside doesn’t drop too low, as this can harm plants. If you plan to grow any winter crops or seedlings, consider using a greenhouse heater to maintain an optimal temperature.

8. Check for Pests and Diseases

Although it’s cold outside, some pests and diseases can still be active during January. Check your plants for any signs of pests such as aphids or slugs, as well as any signs of disease. Overwintering pests may hide under plant debris, so make sure to clean up fallen leaves or plant matter that could harbour harmful pests. If you find any pests, remove them manually or use eco-friendly treatments.

9. Look After Your Lawn

While your lawn will be largely dormant during January, it’s still important to keep it healthy. Avoid walking on your lawn when it’s frozen, as this can damage the grass. If there are any areas where moss has built up, apply a moss killer and remove it once the weather improves. Don’t be tempted to mow the lawn until the grass begins to grow again in spring, as mowing in winter can cause stress to the turf.

10. Prepare for Storms and Wind

January is often windy, and storms can cause damage to plants, fences, and garden structures. Check that any garden structures, such as sheds, greenhouses, or fences, are secure and well-maintained. If you have tall plants or fragile shrubs, consider staking them to prevent them from being blown over. Make sure that any loose garden items, such as pots or tools, are stored away to avoid them becoming wind-blown hazards.

Conclusion

While January is a quiet month for gardening, it’s also a time for winter maintenance and preparation. From protecting your plants from frost and snow, to planning for the spring growing season, there’s plenty of work to be done to ensure your garden is ready for the year ahead. By maintaining your tools, caring for wildlife, and tending to your garden structures, you’ll be well-prepared for the growing season when the weather warms up. Taking small steps now can make a big difference in the health and beauty of your garden in the months to come.
